BOBBIN-TENDER.

Specification of Letters Patent.

Patented June 12, 1917.

i Application filed. July 25, 1916. Serial No. 111,239.

To all rwhom it may concern:

Be it known that I, DANIEL L. CHANDLER, a citizen of the United States, residing at Ayer, in the county of Middlesex and State of Massachusetts, have invented a new and useful Bobbin-Tender, of which the following is a specification.

This invention relates to a machine for automatically supplying bobbins to a bobbin stripping machine or the like.

The principal objects of the invention are to provide a device on which bobbins can be dumped indiscriminately and which will take them in proper manner and cause them to be fed toward the bobbin stripper all in the same direction and at regular intervals and applied thereto; also to provide a novel arrangement of belting for supporting and feeding the bobbins, a simple and practical device for turning end for end the bobbins which are presented in the wrong direction; to provide a timing mechanism for insuring the feeding of the bobbins in time with the operation of the bobbin stripping machine itself; and to provide improvements in details of construction and in other features of the machine.

Reference is to be had tothe accompanyin@ drawings, in whichigure 1 is a plan of a machine constructed in accordance with this invention;

Fig. 2 is a side view of the same;

Fig. 3 is an end view;

Fig. l is a side view on enlarged scale showing the operation of reversing the bobbins that are presented in the wrong position, showing the parts in section on the line l-t of Fig. l; v

Fig. 6 is a sectional view on the line 6-6 of Fig. 1, andA Fig. 7 is a sectional view on the line 7 7 of Fig. l.

Although the principles involved in this machine are capable of application in connection with other machines, yet I have shown it herewith as adapted to feed bobbins to a bobbin stripping machine of the general type shown in several of my prior atents and particularly in Patent No. 1,147,678 patented July 20, 1915. In that machine there is a wheel A provided with radial pins B for receiving the bobbins. It is for the purpose of presenting the bobbins to these pins and applying them thereto that this machine is designed.

The embodiment of the invention shown in these drawings comprises a machine having a frame 10 located adjacent to the wheel A and is provided with a power shaft 11 receivlng power from a pulley 12 or from any other desired source. By means of pulleys 13 and a belt 14 power is transmitted to a second shaft 15 parallel with the first and located near the bobbin stripper end. On this shaft are located a lpair of drumsl which receive two parallel wide feeding belts 17. These belts also pass over a similar pair of drums 18 1,on a'shaft 19 at the other end of the machine. The top strands of these two belts constitute the main portion of the receiving part of the machine. They are wide enough so that they are adapted to receive a basket of bobbins on them and attend to the first part of the feeding operation. They run back away from the bobbin stripper in the direction indicated by the arrows so as to carry the bobbins that are received by them back toward t the rear of the machine.

cated at an inclination so that the belts 24- with` which they are provided form a V- shaped trough for receiving bobbins. This trough is so located at its discharge end that a bobbin located on it will be moved by it on a pin B of the wheel A- when the pin is horizontal. These belts are located between the edges of the belts 17 and it will be observed thatthe two pairs of belts are so inclined that the upper strands of the belts 17 are below the upper strands of the belts Mat the end toward the bobbin stripper, and aboveA them at the other end of the machine. These belts 24 pass over pulleys 25 at the other end of the machine and idlers 26 are provided for guiding the idle strand. The clearance between the edges of these belts is made as small as convenient so that they will not interfere with each other and bobbins are two trips 35.

yet bobbins cannot pass betweenr them. The four upper strands of the belts 17 and 24 constitute the surface on which the bobbins are dumped.

On one of the shafts 22 is located a crank 28 provided with a rod 29l which is connected to a shuffier driving arm 30 pivoted. on` a central vertical stud 31 on the frame. On this stud and fxedly connected with the arm 30 is a V-shaped oscillating shuffler 32 arranged to extend over the surfaces of the two belts 17 and adapted to be oscillated as indicated by the full and dotted lines -in Fig. 1 by the action of the crank 28.

It will be understood that the bobbins are intended to be fedy by the belts 24y being held in the V-shaped trough formed by them and applied to the pins B by4 the motion of these belts forward.

Located along the path of travel of thev Each one is mounted on a cross bar 36 and; provided with a long spring 37 andl a short spring 38 carried by headed pins to permit the trips to yield and tilt upwardly. The purpose of these as will be seen from. reference. to Fig.

4 is to turn a: bobbin endV for endif it startsto move along past these trips wrong end. up.

yThe operation isvery simple as thetrip engages the grooves on the large end of thev bobbin and tips it over about that end as a center. If the bobbin passes through inthe other direction it will be engaged by theY trips in the same way,.but it cannot be tipped.

over because the. center about whichy it would have to turn is at the other extreme.

On a ,longitudinaly shaft 41 is fixed an army 42 located. in position to be engaged and4 osvcillated by each lug. 40 as it moves above it.

A spring 43 normally holds the` shaft in such a position as to. keep the arm 42 so placed as to be engagedv by the next lug. A

. stop44 is shown for limiting the position in this direction. On this shaft'41A is fixed an.

arm 45 which, of course, moves with the lug 40. On the shaft 41 there is fixed onev of the timing stops 46.

The arm 45 is connected by a'link 47 with an arm 4S on a parallel shaft 49. This shaft is provided with another arm 5,0 fixed to it and moving with the arm 48. On this is pivoted a second timing stop 51. Fixed ony a the arm 50 is an arm 52 which is provided with a stop pin 53 for the end of the stopl 51. This arm 52 is provided. with a spring 54 by which theupper end of the timingl stop 51 is held up against the pin 53 normally. The operation of the device is as follows The wheel A being operated intermittently and the beltsy constantly, bobbins are. dumped ony the belts at any convenient point in an indiscriminate manner. Some of the bobbins will' lie inthe trough formed by the belts 24 and will be fed directly towardl the wheel A. Those that are received by the belts 17 are fed in the opposite direction and are fed upwardly to a point above the upper edges of the' belts 24 at the rear end of the machine. The operation of the crank 28 constantly oscillates the shuffler 32 which, aided by the motion of the belts 17, gradually forces these bobbins over into the trough at the center. IftheV bobbins pile up in the trough 'formed by the belts 24 the top ones will be. caused toroll. off on the side belts 17 near the rear. end of the machine and go through the feeding. operation. again without causing any damage.

Bobbins which. are.' arranged with their butt ends foremost pass under the yielding trips 35 without any material disturbance and the. others are turnedi over end for end. The reason. for using two tri-ps is that if the first one fails to work thesecond one will be practically sure to. perform the desired op.- eration.

When. the bobbins come to. the timing stops they will be stopped by one or the other of them. because one is. alwaysV down, and: in Figs. 1V and; 2 a bobbin is shownv stopped. by the second. one-'46. Just before each. pin VB is. brought to horizontal position.v ready to Vreceivea bobbinl one of thelugs 40 lifts the arm. 42 and` oscillatesA the shaft 41. so as tolift the` timing stop 46so as tolet the bobbin indicated these. figures pass. along.` At the same time the arm` 45. is moving down to the dotted line position shown in Fig. 6 and: the shaft 49 turned so. asto bring the arm 50 down to the dotted line positionv shown in Fig. 7. This moves the other timing stop. 51 down into a position to` engage` the head of the next bobbin and. prevent its being fed forward untill the lug passes'thearm. 42. Then. the parts are restored to the first position and' the. next bobbin. is free to*1 pass underthe timingA stop. 51 and into con-. tact with the lowered; timing stop 46 to. await its turn.

In this way it willA be. seen that the machine takes care of the. bobbins. and. insures: their being fed forward properly. No at-, tendant is required for it and: a bobbin` boy can supply bobbins to several.a of these machines withouty trouble. i

Although I have illustrated and described only a singlev form of the invention and shown it asapplied to a bobbin stripping machine of'only onetypel am aware of the fact that modifications can. be made in thev machine andv that it can be applied toother bobbin strippingl machines than the onef shown without departing-from the scope off the invention as expressed in the: claims.

Therefore I do not wish to be limited in these respects, but what I do claim is l. In a machine for feeding bobbins to a bobbin stripper,` the combination of two belts running substantially edge to edge in opposite directions, one of them being below and adapted to receive the bobbins directly from, the other, and an oscillating shuliler for moving the bobbins from one to the other.

9.. In a machine for feeding bobbins to a bobbin stripper, the combination of a pair of belts running in the same direction and spaced apart, and a second pair of belts located between them and located at an angle to each other to form a trough for receiving bobbins and running in the opposite direction.

3. In a machine of the character described, the combination of a pair of belts running in the same direction and spaced apart, a second pair of belts located between them and located at an angle to each other to form a trough for receiving bobbins and running in the opposite direction, the first named pair of belts being located above the second pair at the end toward which the first pair of belts are running and below them at the other end, whereby they can transfer bobbins to the central pair of belts.

4t. In a machine of the character described, the combination of a belt, a second belt located adjacent thereto for receiving bobbins and running in the opposite direction, the first named belt being located above the second one at the end toward which the first belt is running and below it at the other end, whereby it can transfer bobbins to the second belt, and movable means at the high point of the first belt for moving the bobbins on the surface thereof toward the second belt.

5. In a machine of the character described,

the combination of a pair of wide belts forming a surface for the reception of bobbins, said belts being spaced apart, a pair of feeding belts located between them running in the opposite direction and arranged to form a trough for receiving bobbins, and means whereby bobbins placed on the first named belts will be transferred into the trough and fed thereby in the opposite direction.
